Shell medium-sized, solid, slightly umbilicate, strongly carinate at the shoulder of each whorl, where rise some flat triangular extensions that can be true spines, especially in younger specimens. The sculpture is given by weak radial costae crossed by numerous frilly spiral cords.

The mediterranean members of this species have received the name of Latiaxis sentix carcassii Nicolay & Angloy, 1985, after specimens found by A. Carcassi of Cagliari, at circa 380m deep. As noted by the authors, there is no difference at all between their subspecies and the original caribbean sentix described by Bayer in 1971.
